Sleep is an indispensable activity to keep the body and mind healthy. Short sleep duration is likely to cause heart and other internal ailments. However, it is difficult to say that it is possible to get enough sleep time recommended by health care institutions. The Apple research team revealed data collected from more than 42,000 users.
The research team referred to the sleep measurement data collected by the Apple Watch for 4 months from February 1 to June 1, 2022, and calculated the statistics of 42,455 people who shared their sleep data for 10 or more nights among the subjects who participated in the survey at that time. . As a result, the average sleep time per person was 6 hours and 27 minutes.
The American Heart Association recommends 7 to 9 hours of healthy sleep, but only 31.2% of the subjects in this study met this standard. Because the environment varies greatly from state to state in the United States, the researchers reviewed statistics by state. Washington, South Dakota, and Idaho had the highest rates of sleep, and Hawaii, Mississippi, and West Virginia had the lowest rates.
The researchers estimated that differences in daytime sleep patterns are believed to be related to latitude, cultural differences, differences in demographic dynamics such as age, employment type, occupation, and many other factors. However, although levels vary by state, less than 40% of residents in all states meet the recommended sleep hours.
In this study, we investigated not only total sleep time, but also how sleep changes, such as changes in sleep time throughout the night and changes in sleep and wake times. As a result of examining the difference in sleep start time between weekends and weekdays, 66.4% went to bed before midnight on weekdays, but it decreased to 56.6% on weekends.
Irregular sleep start times raise concerns, such as susceptibility to certain diseases. In a study conducted by Harvard University on the elderly, results such as those with large sleep pattern fluctuations had a higher BMI, shorter total sleep time, higher heart rate during sleep, and more likely to develop symptoms of depression. People with irregular sleepers may do well to review their sleeping habits.
The research team said that it shows that many people tend to overestimate their sleep time, and that if you are interested in viewing your sleep metrics without setting up sleep on your Apple Watch yet, use the settings or view sleep data procedure. Related information this placecan be found in
